Here is my data


ColA-ColB-ColC
ABC-1-
ABC-4-
ABC-2-
DEF-4-
DEF-5-
DEF-10-
FGH-19-
FGH-12-
FGH-1-
FGH-4-
FGH-8-


Is there any formula I can use in Column C where it will input a 1 if
the number in Column B is ranked in the top two of Column A, and a 0
if it's not?

So final result would look like:

ColA-ColB-ColC
ABC-1-0
ABC-4-1
ABC-2-1
DEF-4-0
DEF-5-1
DEF-10-1
FGH-19-1
FGH-12-1
FGH-1-0
FGH-4-0
FGH-8-0
FGH-9
